# list_one always has fewer list items than list 2
# both lists have several thousand items in them

list_one = [
    {"acct": "12345a","moref":"dc-12"}, 
    {"acct":"132132","moref":"dc-332"}

list_two = [
    {"acct":"132132","cc":"US","zip":"77722"},
    {"acct": "12345a", "zip":"55512","cc":"US"},
    {"acct":"11132132","cc":"US","zip":"77722"}

# Looking for most efficient way to combine list_one[0] with list_two[1]
# where the acct matches so I end up with a dict like {"acct": "12345a","moref":"dc-12", "zip":"55512","cc":"US"}
